"The memo below was sent to the team at Tiny Speck, the makers of Slack, on July 31st, 2013. It had been a little under seven months since development began and was two weeks before the launch of Slack’s ‘Preview Release’. It is presented verbatim, as written (including original pull-quotes), with two exceptions: the removal of an introductory section discussing launch logistics and replacement of a link which pointed to an internal company resource with the equivalent public link." - × × ×
